Polish Opening: Queenside Defense
Overview
Polish Opening: Queenside Defense is a specific line in the Flank Openings family (ECO A00), arising from a recognised theoretical position.
The Flank Openings group covers flank openings — systems that delay the central pawn break and instead develop pieces and pawns on the wings.
The line arises from 6 plies — specifically the moves 1. b4 e6 2. Bb2 Nf6 3. b5 a6.
The line is a first-level refinement of Polish Opening.
It continues primarily into one named line, Polish Opening: Rooks Swap Line.
